A Francis turbine of diameter 2.0 m develops 4250 KW at 200 rpm under a net head of 25 m. A geometrically similar model of scale ratio 1 : 6 to be tested at a head of 8 m. Estimate discharge developed by model. Assume overall efficiency of 0.85 for both prototype & model.
Enter numerical value using the virtual keypad. Round off where necessary.
